On a cool night you can expose for several minutes. Although this works well and the DSI exhibits fairly low heat-induced noise, it still produces noisy raw pre-processed images. He got it to work but gave up on it as a serious CCD camera. He sent it to me.

Adding filters will reduce the amount of light reaching the chip, so dark current and readout noise will inevitably lead to either considerably longer exposures or much noisier images, which seems to me like a lose-lose situation.
Messing Around with Meade’s DSI-Pro
Then I lock the focus, close down Magnifier, increase the exposure to 2 seconds, move to my target, and center it. By clicking on the ‘Sign Up! This improves image resolution, increases the image dimensions and acts mdade a field de-rotator, as long as your telescope is controlled by AutoStar.
The software is coded in VS. However, for monochrome imaging the DSI-Pro does well enough to be fun to mess around with. Altair Hypercam M V2 mono astronomy imaging camera.
I had to reinstall the USB drivers over and over, and even then it seemed to be hit-or-miss whether my laptop would recognize the DSI when I plugged it in.
The software was buggy and froze up. The Ring Nebula picture was taken in the fall of from my half-completed observatory. Meade had upgraded the software somewhat. In winter, when it’s cooler, the longer exposures might be superior.
When the DSI-Pro was announced, we briefly considered writing a book for new users who were sure to find imaging with these low-end cameras daunting — so I “invested” in a DSI-Pro. Our main concern was the base level of noise it generated. This proved to be true: After a lot of experimenting, I gave up using the Meade software for anything but capturing the raw images.

The aluminum housing is crudely cast and minimally machined. This data is also recorded against dark frames whenever they are generated. In summer, Meade’s software does a good job dark-subtracting second exposures and less well with second exposures. I put the camera into auto mode with a 0. This review appeared in the January issue of Sky at Night Magazine.
Deep Sky Imager (DSI) IV
Cookies perform functions like recognising you each time you visit and delivering advertising messages that are relevant to you. This is a stack of 74 exposures each 15 seconds long, with no ssi or guiding. Post-stack processing with these images was minimal; I used the Brightness Scaling Tool with Sigmoid scaling, and touched up the final contrast before exporting the images you see here.
You can opt-out at any time. I haven’t tried to make color images with this camera.
Deep Sky Imager IV (DSI-IV)
Scott related how he had seen the Cookbook, and was impressed at the speedy image display and overall ease of use. The sensitivity of the camera was terrible. Although their initial attempts to csi the amateur CCD market were flops, it was unlikely that this aggressive company would sit by while others cashed in on anything to do with astronomy.
Focusing is easy because my Newtonian’s diffraction spikes split into msade parallel lines when the image is slightly out of focus.
Bresser full HD deep-sky camera. Although this works well and the DSI exhibits fairly low heat-induced noise, it still produces noisy raw pre-processed images. Envisage is a clever program geared towards getting you the best image possible.
If you already have an AutoStar-controlled telescope, the DSI Pro II should be a serious consideration; the level of integration between software, camera and scope is excellent. To view this digimag, Adobe Flash player is required. Find out where to buy your equipment with our Retailer Guide.
